摘　　要：文章对中美双边微观贸易数据进行整理,并通过面板数据进行经验分析,发现出口产品种类的增加对两国出口产品比较优势的提升均有明显的促进作用;同时,在中高技术产业和中低技术产业的分组回归中又发现,中高技术产业中出口产品种类的增长对比较优势的提升有显著促进作用,但在中低技术产业中则不显著。因此,我国应重视出口产品种类的创新,尤其是中高技术产业内的新产品种类研发,以提升出口产品的国际竞争力并获得更广泛的国际贸易利益。The development of product varieties is becoming not only one of the key factors of gaining international competitiveness but also one of the important sources of trade gains. The paper studies the relationship between comparative advantage and product variety. Its empirical results show that the increasing of product varieties would raise the international competitiveness and comparative advantage of export products. And at the same time, it also finds that the promotion effect is more significant in the high technology industry than that in the low technology industry. Therefore, China should pay more attention to the innovation of export product variety, especially that in the high technology industry, in ordor to obtain more competitiveness and trade gains.
